What is the difference between eye-tracking and brain data for video analysis?

Eye-tracking (or saliency-based tools like AttentionInsight) predicts where a viewer's eyes fixate on a frame — it tells you what they looked at. Brain data (fMRI-based tools like VidCognition) predicts which brain regions activate during each second of video — it tells you whether they were emotionally engaged, cognitively processing, or forming a memory. For short-form video optimization, brain engagement data provides a deeper signal: a viewer can look at a hook without being emotionally compelled by it.

Is VidCognition an AttentionInsight alternative?

They serve different use cases. AttentionInsight is focused on visual saliency for images and design work. VidCognition is focused on brain engagement for short-form video content. If you're a creator analyzing TikTok or Reels performance, VidCognition is the more specific tool. If you're a designer analyzing where eyes go on a static layout, AttentionInsight is more appropriate.

What is AI saliency mapping?

AI saliency mapping predicts which areas of an image or video frame will draw visual attention, based on models trained on human eye-tracking data. It shows 'heat zones' where gaze is most likely to land. This is distinct from fMRI-based brain prediction, which measures full neural engagement including emotional and memory regions — not just where the eyes go.

Eye-Tracking vs Brain Data: AttentionInsight vs VidCognition

AttentionInsight shows you where viewers look. VidCognition shows you what their brain is doing — which regions activate for attention, emotion, and memory encoding — second by second.

Bottom line

AttentionInsight is a strong tool for static image analysis and visual saliency — where do eyes go on a webpage, ad, or product image. For short-form video brain engagement analysis — second-by-second neural activation, hook scoring, and engagement drop-off — VidCognition offers deeper insight using AI-predicted fMRI data.

Eye-Tracking vs Brain Prediction — What's the Difference?

AttentionInsight — Eye-Tracking

Saliency models predict where a viewer's eyes will fixate on an image or video frame. This is useful for understanding visual hierarchy — does the viewer see the product before the headline? Does the call-to-action get noticed? AttentionInsight's AI simulates this gaze path without requiring real human test subjects, at $23/month.

This is genuinely valuable for static design work: packaging, landing pages, ad creatives, billboard layouts. It answers “did they see it?”

VidCognition — fMRI Brain Prediction

fMRI measures blood flow in the brain — which regions are metabolically active during a given second. Meta's TRIBE v2 model was trained on 7T fMRI data from humans watching video content, enabling it to predict not just visual attention, but the full neural response: which brain regions activate, at what intensity, at each second of a video.

This answers deeper questions: “Did the hook trigger the amygdala's emotional response?” “Is the prefrontal cortex engaged or on autopilot?” “Is this moment encoding into memory?” Eye-tracking can't answer these — it only captures where the visual system focused, not what the rest of the brain did.

Which tool is right for you?

Use AttentionInsight if:

You're analyzing static images, landing pages, packaging, or display ads
You need to optimize visual hierarchy (is the CTA visible? does the logo get noticed?)
Your workflow is design-centric and you need image-by-image analysis
You want simulated eye-tracking at a low monthly cost

Use VidCognition if:

You're a short-form video creator (TikTok, Reels, Shorts)
You need a second-by-second brain engagement timeline for your videos
You want to know which brain regions activate during your hook and why
You need hook scoring, engagement drop-off diagnosis, and 3D brain visualization
You want a free tier with no credit card required
